I have worked in an Oreck store part-time for years now, and whenever I see an Oreck come in with a generic bag, there always seems to be a lot of dust leakage around the port and inside the cloth bag. We sell our paper bags for 24.99/8 but even better are the hepa cloth, but pricier at 34.99/8. The hepa bags are the bomb, but even our paper bags filter better than the generics from what I've seen. Depending on your situation whether you have allergies and or pets, the paper bags could suit you well. It takes a lot of vacuuming to fill one of our bags, and most collectors I know vacuum frequently, so filling a bag takes a while, depending on the household that is. Check ebay or craigslist, sometimes if someone's Oreck bit the dust, they sell their bags and I've even seen some in thrift stores on occasion.
